Maiden Voyage lost one engine

[mathewsxt1987]

Well I ended up buying the 2001 challenger with the twin 717. Ran fine when I took it out with the previous owner, and today I decided to take the wife out.

Boat ran good when we first started out, and since one engine was still new I kept it around 5000 to 6000 rpms and never any more.

After a few minutes riding when taking off I had to give the right motor more throttle to bring the rpms up, if I kept the throttles about the same the left motor who reach higher rpms and I wouldn't come out on plane.

About 30 mins later of playing my right engine died, but started back. We swam for a little bit then went riding again. A few mins later the right engine died again and acted as if it didn't wanna turn over but finally started cranking but never started back up.

We headed toward the dock on one engine and when we got close to the dock I decided to try and start the engine. If acted like it fired but never started completely.

All new to sea doo motors so any help would be greatly appreciated. The engine that died is the new one and I think is under warranty. Gotta call the mechanic who out it in tomorrow and fine out for sure. Just looking for advice cause honestly I'd rather work on my own stuff

Another question to add to this post. When running only one engine should I have done anything. I've read somewhere about clamping a hose but can fine it anywhere

With skis, if you are going to exceed 12 mph you need to clamp the coolant hose that comes from the pump to engine. If not, you can fill the exhaust up with water and then it will flow to the top end of the engine and will enter the engine. I don't know what the magic number is for boats, but I imagine it is the same.

I never got over about 5-10. Guess I need to get a owners manual to have more information.

Yeah, every time I wasted an engine in my Speedster I never clamped the line. You can't move fast with just one engine, it's like dragging the anchor.

Bummer on the engine. Hopefully it's covered and hopefully the tech did the carbs when he had it apart. With these old boats you can't skip anything. Once you go thru them you're good to go for a while.

The engine was actually ordered from a company in Florida. Figured I'd check the plugs and compression tomorrow just to have an idea.
